Concept:
Investment Fluctuation Reserve (IFR) is a reserve created to cover possible losses arising from a fall in the market value of investments.
At the time of retirement or death of a partner:
• all accumulated reserves and profits must be distributed among all partners,
• unless the reserve is still required for a known liability or reduction in asset value.
Thus, before distributing the reserve:
• first adjust the fall in investment value,
• then distribute the remaining balance among all partners in their old profit-sharing ratio.
Step 1: Understanding the treatment of Investment Fluctuation Reserve.
Suppose:
\[
\text{Investment Fluctuation Reserve} = ₹50,000
\]
and actual fall in value of investments:
\[
= ₹20,000
\]
Then:
\[
\text{Remaining Reserve} = 50,000 - 20,000 = ₹30,000
\]
This remaining amount is no longer required.
Therefore, it becomes accumulated profit and must be distributed among all partners.
Step 2: Accounting treatment.
The journal entry for distributing remaining reserve is:
\[
\text{Investment Fluctuation Reserve A/c Dr.}
\]
\[
\text{To All Partners' Capital A/cs}
\]
Thus, the reserve account is debited and partners' capital accounts are credited.
Step 3: Evaluating options carefully.
Option (A):
\[
\text{Credited to Revaluation Account}
\]
Incorrect because reserve balance is transferred directly to partners' capital accounts and not to revaluation account.
Option (B):
\[
\text{Credited to All Partner's Capital Accounts}
\]
Correct because the remaining reserve after adjustment belongs to all partners.
Option (C):
\[
\text{Debited to Deceased Partner's Capital Account}
\]
Incorrect because reserve is not a loss after adjustment.
Option (D):
\[
\text{Credited to Deceased Partner's Capital Account}
\]
Incorrect because the reserve belongs to all partners, not only the deceased partner.
Final Conclusion:
The balance amount in Investment Fluctuation Reserve after meeting fall in value of investments is:
\[
\boxed{\text{Credited to All Partners' Capital Accounts}}
\]
Hence, the correct answer is:
\[
\boxed{\text{(B)}}
\]
